Major Inorganic components of Bone :-

Options

A. Calcium phosphate
B. Calcium carbonate
C. Sodium hydroxide
D. Potassium hydroxide

Answer

### Step-by-Step Solution:

1. **Understanding Bone Composition**: Bones are made up of both organic and inorganic components. The inorganic components primarily consist of various salts.

2. **Identifying Major Inorganic Salts**: The major inorganic components of bone are primarily calcium and phosphorus. These elements combine to form specific compounds.

3. **Recognizing the Key Compound**: The most significant inorganic compound found in bone is calcium phosphate. This compound provides strength and rigidity to the bone structure.

4. **Evaluating Other Options**:
- **Calcium Carbonate**: While it is present in some bones, it is not the major inorganic component.
- **Sodium Hydroxide and Potassium Hydroxide**: These compounds are not typically found in bone structure and do not contribute to its composition.

5. **Conclusion**: Based on the analysis, the major inorganic component of bone is calcium phosphate.

### Final Answer:
The major inorganic component of bone is **Calcium Phosphate** (Option 1).
